You could use unsigned ints, whose arithmetic wraps, to deal with the overflow.

I'd still be curious about any theories of storage.

Javacript doesn't have an unsigned int datatype. The numbers in the article were doubles.

you cant swap doubles like that though... b/c if any of them is a NaN or an infinity, it breaks down.

It works for integers (and pointers)

It also breaks due to rounding even if you don't have NaN or Inf.
